利用php中mail函数发送带有附件的邮件

mail函数,发送邮件

语法： mail(to,subject,message,headers,parameters)

to 规定邮件的接收者 

subject 规定邮件的主题。该参数不能包含任何换行字符 

message 规定要发送的消息 

headers 规定额外的报头，比如 From, Cc 以及 Bcc 

parameters 规定 sendmail 程序的额外参数。 

碰到的主要问题是乱码问题,刚开始是某些客户端接收邮件时好(比如QQ邮箱,估计带自动那个识别编码)的有些不foxmail、ipad显示乱码,解决方式正确的设置这个mail的headers就行了,下面是我使用的完美的无乱码的例子。

在PHP中配置php.ini文件过程分为两个步骤：

1.先找到你放置所有PHP，Apache，MySQL文件的地方，在PHP文件夹里你可以发现有一个文件：php.ini，打开后，找到mail function地方，将原来的配置代码改为如下（仅对windows系统）：

[mail function] 
; For Win32 only. 
SMTP =smtp.sohu.com     
mtp_port=25 
; For Win32 only.

sendmail_from = 填上你的电子邮件全称。 

此处为以sohu的邮件服务器设置,如果你用163的邮箱,则设置为:smtp.163.com

2.在C盘搜索php.ini,选择不是快捷方式的那一个php.ini,应该在C/WINDOWS里面的，打开它，如上面一样修改它,保存,设置完后,记得重启Apache服务器,然后mail()函数就可以用了,示例代码如下:

<?php
// 当发送 HTML 电子邮件时，请始终设置 content-type
$headers = "MIME-Version: 1.0" . "rn";
$headers.= "Content-type:text/html; charset=utf-8";
mail($to, $subject, $message, $headers);
?>

上面函数不可以带附件了,下面我们升级一下,代码如下:

<?php
class Mail {
    private $topic;
    private $toaddr;
    private $fromaddr;
    private $cc;
    private $content;
    private $attach;
    private $header;
    private $domain; //邮箱域
    private $msg;
    private $filename;
    private $filemime;
    private $filestr;
    private $boundary;
    private $uniqid;
    private $eol; //每行末尾所加的换行符类型
    function __construct() {
        $this->getEOT(); //生成结尾换行符
        $this->getUniq_id();
        $this->header = &#39;&#39;;
        $this->attach = &#39;&#39;;
        $this->cc = &#39;&#39;;
        $this->msg = &#39;&#39;;
    }
    public function getFromaddr() {
        return $this->fromaddr;
    }
    public function setFromaddr($fromaddr) {
        $this->fromaddr = $fromaddr;
    }
    public function getTopic() {
        return $this->topic;
    }

        return $this->toaddr;
    }

        return $this->cc;
    }

        return $this->content;
    }
    public function getAttach() {
        return $this->attach;
    }

        $this->topic = mb_convert_encoding(trim($topic) , &#39;UTF-8&#39;, &#39;auto&#39;);

            return $this->mailWithAttach();
        } else if (!emptyempty($this->toaddr) && !emptyempty($this->topic) && !emptyempty($this->cc) && !emptyempty($this->content) && !emptyempty($this->attach)) {

            $this->getBoundary(); //有附件就生成boundary

            return $this->mailAll();

        }

    }

}

?>

示例代码,有些变量需要上下文环境,代码如下:

<?php
$m = new Mail();
$m->setToaddr($this->temp[&#39;receipt_address&#39;]);
$m->setTopic($this->temp[&#39;mail_title&#39;]);
$m->setContent($this->temp[&#39;mail_content&#39;]);
$m->setFromaddr($_SESSION[&#39;user&#39;][&#39;name&#39;] . &#39; <&#39; . $_SESSION[&#39;user&#39;][&#39;name&#39;] . &#39;@&#39; . SystemDomain . &#39;>&#39;);
$m->setDomain(&#39;@&#39; . SystemDomain);
$m->setCc($this->temp[&#39;cc_address&#39;]);
$m->setAttach(PATH . &#39;/temp/&#39; . $this->temp[&#39;attachment_file&#39;]);
$m->send();
?>

优点：使用方便就一个简单的函数

缺点：需要php.ini支持该函数，如果某些服务器不支持而又不能改环境那就不行了而且总是不稳定，发的有时能收到有时不能.
